IAR memory view for stm32N6 PSRAM

[GanZ]

I am not able to view stm32N6 PSRAM @ 0x90000000 with IAR Memory view, it only shows --. And after I tried to access 0x90000000, the debugger seemed to hang up.

I tried with STM32N6570-DK XPI_PSRAM_MemoryMapped project. I set a breakpoint at line 197 -- if (errorBuffer == 0) after it read/wrote PSRAM successfully. When it stopped at the breakpoint, I opened the memory view to check memory @0x90000000. It failed.

If I did the similar with stm32CubeIDE, it worked fine.  

Any idea why the IAR was not working?

You should be asking IAR this question - it's their product !
